SOFA-BED.

SPECIFICATION forming part of Letters Patent No. 322,643, dated July 21,1885.

Application filed March 28,1884.

To all whom, it may concern:

Be it known that I, GEORGE W. RoBBINs, of Los Angeles, in the county ofLos Angeles and State of California, have invented a new and usefulImprovementin Sofa-Beds,of which the following is a full, clear, andexact description.

This invention pertainsto improvements in sofa-beds, which, asindicated, are convertible to serve either as a sofa or as a bed; and

I the same consists of the combination of parts and their construction,substantially as hereinafter fully set forth and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a front elevation of my improved sofa'bed-with the back setupright and with a part of the frame in longitudinal section. Fig. 2 isa transverse section of the same with the back set upright. Fig. 3 is anend elevation with back turned down for a bed.

The back frame,a,is hinged to the main frame b by the jointed bars 0,whose pivots d are located sufficiently above the top of the back rail,6, of the main frame bto support the back frame, a, sufficiently aboveand back of said rail 6 to allow the back frame, a, to swing down behindframe I) and level with it, to rest at the back of said frame a whendown on the outer side rail, f,of the clothes drawer g, which is fittedto slide in and out of the back of the frame I). To the back frame, a,thus hinged to the main frame I), I hinge a pair of short legs, h, at i,so as to swing directly under said frame when it is set upright tosupport it; and for the support of these legs I extend the guide bars ofthe main frame I), on which the drawer 9 runs, so far back of the (Nomodel.)

rear of frame I) as the back a is extended when set upright, and theseextensions are supported back of the frame I) by the drawer, which hasgrooves k,in which one edge of the guides rests, and the drawer rests onthe floor. In practice the drawer will have casters to roll and rest on.The drawer is fitted so that the back end projects even with theextension of back a, behind frame b when said drawer is shoved in frameI; to the end of its range. so that it always supports the guidesj whenthe back a sets upright and rests on them. The joint-bars c are arrangedat about forty-five degrees of inclination to the frames I) and a, sothat when back a sets upright and sustains the pressure of personssitting on the sofa the pressure on the back mainly thrusts directlydownward on the legs 11, which afford sub stantial support to the back,and with said joint-bars make ample means of effectually maintaining itin position.

Having thus described my invention, Iclaim as new and desire to secureby Letters Patent The combination, with the main frame having cleats orrails projecting beyond the rear sides of said frame, of the back framejointed to the main frame, and the auxiliary frame with its longitudinalbar hinged to the lower edge of the back frame,to permit its side barsto rest upon the projections or extensions of the said cleats or railsin supporting the back 'frame in an upright position, and to. foldunderneath the said back frame in lowering the latter into a horizontalposition, substantially as and for the purpose set forth.

GEORGE W. ROBBINS.
